Abstract

The invention relates to a composition and a porous ceramic atomization core containing a continuous glass phase, the composition comprises powder, the powder comprises the following components by mass: 50-60% of ceramic powder, 15-19% of a sintering aid, and the balance of a pore forming agent, the sintering aid comprises glass powder, the glass powder comprises low-melting-point glass powder, the softening point of the low-melting-point glass powder is 400-500 DEG C. As the glass powder different from the glass powder in the prior art is selected, the microstructure of the prepared porous ceramic atomization core has a continuous glass phase, so that the inner surface of a pore channel is smoother, the contact angle is effectively reduced, the oil guide performance is improved on the premise of not increasing the pore diameter, meanwhile, the oil locking capacity is improved, and oil leakage and core pasting are not likely to happen.

Description

Technical field [0001] The present invention relates to the field of electronic cigarettes, and more particularly to a composition and a porous ceramic atomization core containing a continuous glass phase. Background technique [0002] The existing electronic cigarette porous ceramic atomization core consists of a ceramic powder with a glass, wherein the ceramic powder acts as a support structure, and the glass phase is dispersed between the powder to bond the ceramic powder. The pores of the porous ceramic come from the natural accumulation between the ceramic powder and the addition of the pore agents. [0003] Existing porous ceramic atomization cores have problems such as oil, and vibrant cores. In order to improve the oil capacity, the common solution is to increase the pore size of the porous ceramic to increase the oil volume, but the disadvantage of the program is to increase the risk of the homogenic core leakage. Inventive content [0004] According to the first aspect...
